can anyone who have use both of these servos please give a flight comparison between the two servos i don't really need HV just in flight stability i'm currently using the BLS451 and it works very well i just wanted to see if there's a better servo out there for stability and sports flying...

the BLS451's are a very smooth and precise servo. However, I feel they do suffer from a performance "issue" I've noticed. Most people probably wouldn't notice of feel this issue, but what I can tell is that they seem to lack immediate torque and take a split second to power up to full torque. I'm probably not explaining it correctly, but say I'm coming around in a fast inverted hurricaine and as I break out and the helis on it's side, and I want to bang on some aileron tic toc's, the heli seems to take a sec or two to get going back and forth. Once it's banging back and forth it's fine and fast, but that "umph" needed at first to yank the heli around off a previous position seems lacking.

The Outrage servos are made by MKS and I've used about 6 sets of MKS BLS servos in various builds, both High voltage and their 6v BLS servos and I don't notice any bad behaviors from them. They seem to have more speed and torque in the air, even comparing similar spec servos like the BLS451 vs the MKS BL950, the MKS blows away the feel of the BLS451 in the air at least to me.

To be fair, I haven't really flown the BLS253 or HV BLS Futabas so that issue I've noticed on the BLS451 may have been corrected. Plus the BLS451 is a car servo and has some more deadband programmed in, so that may be what I feel in the air compared to other brands.

What you are feeling in the BLS451 is there. They are programmed to be stable and smooth. That's what I like about them. I fly more sport FAI type of stuff. The BLS253 is programmed for snickity-snacky 3D stuff. But they are $40 more.

Then it sounds like you have the best servo for your style of flying.

don't forget about the power supply for the servos. i had the align 2in1 running all stock align servos in a t700n and i noticed the difference when i changed to gryphon. all were on 6v with the 2in1, the feel in rolls and flips were fast in the beginning and kinda slowed down after. with the gryphon, the feel was consistent throughout we can use great servos but if the power supplying them isn't consistent, they won't perform consistently
